series CN

The CN series clean-break couplings (dry couplings) have been developed for the safe transfer of large volumes of liquids and gases. As robust disconnect, connect and sealing points, they are used in particular in the chemical industry, with liquid foodstuffs and with a wide range of Group 1 media, such as hydrogen. A secure, splash-free connection is crucial here.

Depending on the technical conditions, the CN series clean-break couplings reliably prevent any media leakage without exception. They also enable controlled coupling even with lines filled and under a residual pressure of up to 8 bar. Taken together, this results in safe, splash-free and trouble-free coupling and uncoupling, even with hose lines filled in this way, thereby enhancing process reliability and ergonomics, for example when loading large volumes.

As a low-pressure clean-break quick-coupling system with a cam-lock mechanism, they are primarily used for handling correspondingly large volumes at loading stations for lorries or trains carrying chemical liquids, liquid foodstuffs or their base materials and additives, as dry couplings, dry-connect couplings or dry-break couplings. They offer extremely ergonomic two-hand operation thanks to a smooth-running rotating sleeve, which the operator can actuate either directly by hand or, optionally, using a handwheel, without any significant effort. Further areas of application include use as a drip-free refuelling coupling.

For the high-volume transport of dangerous goods by road and rail, the CN series holds a TÜV certificate of type approval for the manufacture of transportable pressure equipment in accordance with Directive 2010/35/EU in conjunction with ADR/RID 2017 and DIN EN 14432:2014 → more information
